To clarify: he has gone on one field trip with her and now they are away together with a couple friends this weekend for fun.
He paid my way through two years of college a few years back and now I am helping him through one year of university. We are common law and have been living together for 8 1/2 years.
I admit I am more concerned about the unwillingness to say he wants to be with me forever. I can live with separation if I know we still have a future.
He is very unattached to life in general. I admire that quality in him. If he lost everything he has in this world - including me - he would still be quite peaceful. I am not so enlightened and I truly fear losing him.
